Batteries
Crucial for operating everything from toys to remote controls, batteries are a must-have item around the house. The problem with Walmart, however, is that you’ll likely spend a lot on batteries and get little in return.
Right now, the retailer offers a four-pack of Energizer Ultimate AA Lithium Batteries for $6.94. But if you buy in bulk at Sam’s Club, you’ll get an 18-pack of the batteries for $19.98.
